A great productby Timothy from Bennettsville, South Carolina on October 21, 2013

I once used the disposable air horns, my employees would go thru about 6 cans per month but since we have started using the refillable air horns 2 years ago I have only had to purchase replacements for those that got lost. I would advise anyone who uses air horns on a daily bases to give them a try, they are a cost saver, reliable and reduce waste going to the landfill. TIM THE SAFETY MAN

It worksby James from Erie, Pennsylvania on July 12, 2013

My yacht club rule is "sound horn entering and leaving channel". I use a horn a lot. Sound is plenty loud and sounds like a horn, not like the electric hand-held horns. I use the Coast Guard prolonged signal of 4-6 sec. only get a few. You can tell when it needs pumped up with a hand squeeze. Pump up is EZ.
